fLReferring to therfdraawingaitfwillzbeifseenuthat .55 -curtainsl'lsufianda I Isfare identical in;;constructien 3 except that they are right and left hand, as will be obvious. A description of curtain I0, therefore, will sufice for a disclosure of any invention.

The curtain lil, as is clearly shown in Figure 2, comprises a body portion in the form of a panel I2 which is made of flexible material, and which has secured to its top a valance I3 provided'with a channeled portion I4, the latter having a curtain rod I6 passed therethrough. The inner vertical edge I'I and the bottom edge I8 of the curtain IB are shown provided with an ornamental ruiile or fringe I9, while the outer vertical edge 2I of the curtain I0 is shown Without a ruille.

Across a mid portion of the vpanel I2 extends an elongated tie-back construction 22 comprising a warp knitted band of material 23 and a draw tape 24. The band 23 comprises a pair of spaced parallel runs of material or headings 23 26 each formed by a warped strand alternately making a series of short loops 2'I and then a pair of long loops 23, each pair of the latter constituting a transverse run of material that is disposed to extend across to an opposed portion of the other heading, overlying the opposed portion for securement thereto by three parallel runnings of chain stitched strands 23, the headings 2li-26 and the spaced pairs of long loops 28 thereby forming an open ladder-like structure. The draw tape 24 is rove through the openings between the aforementioned spaced pairs of long loops 28 so that the latter alternately loverlie opposite faces of the draw tape, as clearly shown in Figure 5.

The band 23 is secured to the panel I2 by lines of stitches 36-36 along the full length of headings 2li- 26, and the inner end portion of draw tape 24 may be secured to the inner edge of panel I2 by the same stitches that secure the ruffle I9 thereto.

The draw tape 24 is of such a length that it protrudes outwardly beyond the outer edge 2i of panel I2. By pulling on this protruding free end of the draw tape 24, the panel I2 and all of the warp knitted band 23 except the long loops 28 which overlie the outside face of draw tape 24 are gathered or folded on one side of draw tape 24, while the long loops 28 which overlie the outside face of draw tape 24 are gathered on the other side thereof.

In use, the curtain I0, after being hung, is adjusted by means of the draw tape 24 until the desired effect is obtained, after which the draw tape 24 may be secured to a suitable fastening device 32 in order to cause the curtain to hang with its outer edge 2I in a vertical position, or if free hanging of the curtain is desired, the securing may be dispensed with while the gathering is, nevertheless, retained.

If desired, a strip of ornamental material 3I may be disposed between the tie-back construction 22 and the panel I2, the Warp knitted band of material 23 being sewed to the panel I2 through the ornamental strip of material 3l, as best shown in Figure 4, and in such case it will be noted that the ornamental strip of material 3I folds on one side of draw tape 24 with panel I2 and all of the warp knitted band 23 except the long loops 28 which overlie the outside face of draw tape 24, while the long loops 28 which overlie the outside face of draw tape 24 are gathered on the other side of draw tape 24, as best shown in Figure 6. Also, if desired, the strip of ornamental material 3| may be disposed on one side of the panel I2, While the tie-back construction 22 is disposed on the other side thereof, and in this case, too, the ornamental strip of material 3I folds on one side of draw tape 24 with panel I2 and all of the warp knitted band 23 except the long loops 28 which overlie the outside face of draw tape 24, while the long loops 28 which overlie the outside face of draw tape 24 are gathered on the other side of draw tape 24.

In assembling the parts of the curtain, the operator may handle the tie-back construction 22 as a unit since the warp knitted band of material 23 can be furnished with the draw tape 24 already rove in place. Also, it will be seen that the open construction of the warp knitted band of material 23 dispenses with pockets in which dirt might lodge, which makes applicants arrangement desirable from the standpoint of laundering. The open construction of the warp knitted band of material 23 is also desirable from the standpoint of ironing and straightening out the draw tape 24 when it becomes twisted. With regard to ironing, since the draw tape 24 is flat there is no undue bulk to prevent proper ironing of the material in the proximity of the tie-back construction 22. In addition, the open construction of the warp knitted band of material 23 facilitates straightening out the draw tape 24 throughout its entire length when it becomes twisted. Thus, it is possible to iron the draw tape 24 in place, and, if desired, it may be separated from the warp knitted band of material 23 by pulling it through at the inner edge I'I of panel I2, ironed throughout its entire length, and then replaced. It will be seen that due to the open construe tion of the Warp knitted band of material 23 and the fact that the headings 26-26 thereof are secured to the panel I2 by stitches which are separate from those securing the inner end portion of draw tape 24 to the inner edge I'I lof panel I2, the draw tape 24 may be replaced Without disturbing the warp knitted band of material 23.

It will also be seen that since there is never any bulk of material on one side of the draw tape 24, there is no resistance to graceful folding of the material on the other side. In this connection, it will be observed that the curtain may be drawn up tighter than would otherwise be possible, and that, consequently, the curtain may be draped to give a novel appearance. Still further, it will be noted that the curtain presents the same graceful folds Whether the tie-back construction 22 is disposed on one side or the other thereof, and whether a strip of ornamental material 3| is used or not, either on the same side of the curtain as the tie-back construction 22 or on the opposite side thereof. And still further, it will be noted Vthat the appearance of the folds is not marred in any way by exposure of the tie-back construction 22 to view.

If desired, as shown in Figure 7, the tie-back arrangement of the present invention may include an additional draw tape 24 which extends in closely spaced parallel relation to the tape 24, this additional tape being rove through and retained in position by its own warp knitted band 23. The corresponding inner ends of both the tape 24 and its retaining band 23 are secured to the inner end of the curtain in the same manner as are the tape 24 and its band 23. In certain cases the band 23 may be warp knitted as an integral part of the band 24, the resultant structure being so formed asto provide a pair of messias? @condition byfdrawi-nglthe'free endsofboth tapes izoutwardlyiofthe curtaini and then tyingl themL-together; .preferably .intoutheiorm sofa aj decorative isbow. knot.
